figure out if the temperature of the reaction would rise‚ will the absorption rise as well. Reactions use energy‚ If there is energy than heat occurs. The Hypothesis that was figured out was‚ If the temperature rises‚ then the absorption will also go up. The Independent variable that was tested was temperature. The dependent variable that was being tested was color and absorption. The data was calculated by a spectrophotometer. The control group of this experiment was room temperature. The constant variables

during the reaction By extrapolating the graph we can estimate what the rise in temperature would have been if the reaction had taken place instantaneously. I can conclude that if the reaction had taken place instantaneously‚ the solution would have reached a temperature of 450C. * Calculate mass of the copper sulphate solution: mass = volume x density = 25 x 1 = 25 g * Calculate change in temperature when the zinc is added: ΔT = Tmaximum - Tminimum = 45 – 20 = 25 0C * Calculate

0 mL water at 25.0 °C . The final temperature of the water and metal was 28.1 °C. Assuming no loss of energy to the surroundings calculate: a) How many joules of energy did the water absorb? b) How many joules of energy did the metal lose? c) What is the heat capacity of the metal? d) What is the specific heat capacity of metal? 2) A 0.400 kg aluminum kettle contains 2.00 kg of water at 15.0 oC. How much heat is required to raise the temperature of the water (and kettle) to 100 C

In the dry climates of Africa one may see the mud huts designed to keep temperatures moderate in the inside while providing a stable structure capable of bearing the heat of the dry savanna‚ while in the cold northern lands igloos are built in order to keep out the cold and provide a haven for the people living within them.

tanker and the amount of oxygen in the tanker. There are two laws that can possibly explain why the tanker imploded. One of the laws is Charles’‚ this law basically explains that there is a relationship between temperature and volume. When heat is added to a liquid volume and temperature increase‚ but in a molecular level the molecules move faster bouncing around in the container it’s in. The equation to Charles’ is V1/T1 = V2T2 .One of other laws is Boyle’s‚ the law deals with the relationship of

plants try to suck up the water from the soil (1). The purpose of this lab is to show clearly in an understandable way how diffusion and osmosis happen and to help one realize the way they occur. If a cube of beat is put in hot water (5 trials – 5 temperatures: 60 ºC‚ 70 ºC‚ 80 ºC‚ 90 ºC‚ and 100ºC)‚ then the mass of the beat cube will decrease because thanks to osmosis‚ water will move from the beat to the clear water outside it‚ because in osmosis water would move from places with low to places with

Northern and southwest parts of the country experienced a rapid fall in temperature on 1 January 2010. Temperatures remained low since‚ with cold winds and serve fog. Poor people in the northern region of the country were the worst affected. The impact of the cold wave had resulted in a significant rise in respiratory illnesses‚ and in some cases
